Assuming we want to continue to build with setuptools, this means converting our packages' current setup.py to setup.cfg, then adding a (boilerplate) setup.py and pyproject.toml to them.

Reasons to do this:

• Gives us the option to build packages using other systems in the future if we need or want that for any reason.
• In my experience, maintining setup.cfg is nicer than setup.py, since it's more declarative.
• Some of the interfaces of setup.py are deprecated (I think we're already getting warnings about this), and this gives us a clear migration path off those too.

Background reading:

• PyPA documentation
• The PEPs
• Brett Cannon blogs: 1, 2
• Here's a commit of me converting a project at a previous job so you can see what it looks like in action
